Patent

CA 2668547

In order to protect a software program, at least one corruption function is included in the program. Also included in the program is at least one instruction that causes the program to be directed to the corruption function. An available breakpoint is then set such that, when the starting location of the corruption function is reached, an exception is generated and the handling of the exception causes the corruption function not to run. This has the effect that, if a malicious user attempts to use the available hardware breakpoint to perform unauthorized actions on the software program, the corruption function will run, and the software program will be unusable.
